Jean-Paul Chaput a6f61c1044 Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
    the new format. So now we can use again SxLib-2M (channel routing
    SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
    AllianceFramework, then try in the Blif supplied libraries.
    This is used to load the zero, one and tie cells.
      Add a Blif::getCell() static function to look into the Blif
    supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
    the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
    routing layers that are *not* presents in the Coriolis gauge.

* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
    as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
    if they are "jumpers" (turn+turn and top+top or bot+bot).
      This case arise on the edge of routing channels for fixed wires
    to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
    (leftBound,rightBound) interval when in channel mode.
       In over-the-cell mode, this interval is the one of the whole
    GCells under the wire. In channel mode, for fixed wires (that is,
    verticals connecteds to cells) this interval is reduced to half
    the GCell height, on the connected side of said channel.
      This allows Manipulator::_insertToTrack() to issue disantangling
    requests (push left/push right) for fixed segments that are face
    to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
    different name from the routingGauge. Now if the cell gauge that
    should match the routing gauge is not found, fallback to the
    name set in "anabatic.cellGauge" parameter.
      Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
    Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
    flag in channel mode. This flag makes sense when there is at least
    4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
    grid point is outside the constraint box. Now force the point
    to remains inside constraints even if offgrid.

* Change: In Katana::DataNegociate::update(), perpandiculars that are
    either reduced or in non-preferred routing direction should not
    trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
    non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
    to free. The intersection function of intervals returns true when
    the two intervals *exactly* touches (1.vMax == 2.vMin). But in
    this specific case, they are not *overlapping* and no action
    should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
    we are overlapping a fixed vertical segment in channel mode.
    (Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
    not put two overlaping vertical fixed segments into infinite cost.
    This happens when two cell connected verticals are face to face in
    a channel. We want them negociated the track (by shrinking their
    length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
    do not attempt to create a track segment over a fixed and reduced
    AutoSegment.
      Do not attempt to put a non-preferred AutoSegment on a Track
    either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
    was badly computed when in the pure constraint case, when there
    was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
    do not issue a bug when an non-pref or reduced AutoSegment do not
    have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
    perpandicular is reduded or non-pref and do not have a TrackElement.

Jean-Paul Chaput 757b95343b Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
    Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
    unload Python modules prior to a full reset.
      Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
    the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
    the library list is empty. Should never occur except in case of a
    botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
    the catalog of a library and "saveCells()" to write back the cells.
      Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
    of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
    (improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
    instead of a static one. This allow for it's correct resetting
    across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
    parser call. Needed to support database reset.

* New: In Hurricane::DBo, add an object counter to be sure that when
    we perform a reset, no remaining DBo is allocated. This is different
    of the object id which is ever increasing.
      Note that, at reset, we check against "1" remaining element as at
    this point only Database is still allocated.
      Add a new "resetId()" method. MUST NEVER BE CALLED except by
    DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
    of all the libraries in reverse hierarchical depth order.
    Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
    DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
    a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
    loop of deletion over a collection for the shared pathes.
      Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
    prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
    various "qtFree()" of the sub-objects.
